To all whom it may concern.

Be it knownthat ILEPPA H. RYoN, a citizen of the United States, residing at Waltham, in the county of Middlesex and State of Massachusetts, have invented certain new. and useful Improvements in Weft- Replenishing Looms, of which the follow ing is a specification.

My invention relates to automatic weft replenishing looms, and particularly to the magazine of a weft replenishing loom, which holds the bobbins or filling carriers,

which are automatically supplied to the shuttle at the magazine end of the loom, upon the practical or substantial exhaustion of fillin in the active shuttle.

. The 0 ject of my invention is to provide a magazine capable of containing a large number of bobbins or'filling carriers, preferably of the same "color or character,

' which bobbins are successively moved to-. ward the discharging end of the magazine,

and the first bobbin/is moved into a position under the transferrer, preparatory to being transferred into the active shuttle to take the place of the substanially exhausted bobbin therein, on the indication of the fillingldetecting mechanism. I

y improved magazine has a spiral guide-way or groove for the bobbins, starting from the centralpart of the maga-- zine, and aiso has means forunovin the bobbinsin the groove, towardthe disc arging end of the magazine, and into a position to be transferred.

My improved magazine consists preferably of a rotatably mounted .part, comprising two disks, each having a,spiral guideway or groove therein, one for the butts, and the other for the t' s of 'the bobbins, and a stationary part eading. from the of sai rotatably mounted part, and a s ring actuated pusher for moving the bobbins toward the discharging end of the magazine, and into a position to be transferred. I also provide means, combined with the magazine, to support the filling threads in a central osition relative to the magazine, and separa e means to hold the ends of said threads.

My invention consists in certain novel understand the construction and operation thereof. v I

Referring to the drawings Figure 1 is a side View of some parts of'a weft replenishing loom, and my improved magazine attached thereto; the magazine is shown in section, on line 1, 1, Fig. 2,100]:- mg in the direction of arrow a, samefigure. The lay and sationary shuttle box thereon are also shown in section. Fig. 2 is a section, on line 2, 2, Fig. 1, looking in the direction of arrow '6, same figure; some of the parts shown in the lower art of Fig. 1 are not shown in this figure. Fig. 3 is an inner end view of the magazine, looking in the direction of arrow 0, Fig.2. Fig. 4 is an outer end view of the magazine, looking in the direction of arrow a, Fig. 1. Fig. 5 corresponds to Fig. 3, but shows the magazine in a difierent position. Fig. 6 shows the pusher mechanism shown in Fig. 3, detached, and with its cover removed, and, Fig. 7 is a plan view of the parts shown in f Fig. 6, looking in the direction of arrow at, same figure.

In the accompanying drawings, 1, Fig. 1, is a port-ion of a loom side or end frame, 2 is the lay with a single shuttle box 3 thereon, containing a shuttle 4:, which carriesa bobbin or filling carrier 5. A feeler on fill ing detector, of any usual construction, not shown, is adapted to enter through the opening 4' in the front side of the shuttle 4 to engage the filling on the filling carrier 5, and to operate, throu h intermediate connections, not shown, t e upright lever B, which has its hub 6 securedon a rock shaft 7, which is suitably mounted in bearings on the filling detector bed, not shown. The upright lever 6 has pivotally connected to its upper end one end of a rod 8, the other end of said rod 8 is adapted to bear against a lug 9 on a downwardly extending latch 9, which has its huh pivotally mounted on a stud 10 on a transferrer arm 11. A helically coiled contraction spring 12 has one end connected to the lug 9, and its other end connected to the rod 8, and acts to yieldingly hold the end of the rod 8 against the lug 9 The latch 9.has its lower end hooked All of the above mentioned parts may be ofthe usual and well known construction.

I will now describe my improvements in the magazine for the bobbins or filling carriers. Rigidly connected to the side 1' of the loom isa stand 14, whichcarries a stud 15, see Fig. 1, on which is pivotally mounted the hub 11 of the transferrer arm 11, in the usual wa An upwardly extending arm on the stan 14 has a boss 14, see Fig. 2, in which is secured, by a nut 16, a horizo'ntally extending stud or shaft 17, which has loosely mounted thereon the. magazine for bobbins or-filling carriers '5. The magazine consists in this instance of the inner end 18, see Fig. 2, for the butt 5' of the bobbins 5, and the outer end 19 for thetips 5" of the bobbins 5. The inner end 18 has its hub 18 loosely mounted on. the stud 17, and extending outwardly from said hub 18 is a sleeve 18", which has mounted on its outer end and fast thereon the hub 19 of the outer end 19 of the magazine, which end holds and guides the tips 5 of the bobbins 5.

The inner end 18 of the magazine is pro-' vided with a guideway for the butts 5 of the bobbins 5, which guideway consists of a groove 18 which in this instance extends in spiral form from the center of the magazine to the outer open-end 18, see Fig. 1. The outer end 19 of the magazine is also provided with a corresponding guideway orv groove 19" of spiral form, for the tips. 5" of the bobbins 5. The guideway or groove 19 extends from'the center of the magazine to the open end 19, see Fig. 4.

The bobbins 5, which are inserted into the guideways 18" and 19 of the magazine and loosely held thereinfare forced from the center of the magazine toward the open end, in this instance by a; pusher. The pusher for the bobbins, see Figs. 1 and 2, consists in this instance of a bar or arm 20, which extends loosely through a groove 18 in the inner end 18 of the magazine,

- and is adapted'to engage the innermost bobf bin 5 therein. The bar or arm 20 is provided with a guide block 20 on its outer 21 in one direction, and to force the bar 20 thereon against the innermost bobbin 5 in the magazine, see Fig. 1.

Aratchet gear 24, which in this instance is made integral with the arms 21, isadapted to be engaged by a lever 25, as shown in Fig. 5, to hold the ratchet 24, and the operating arms 21 thereon. The lever 25 has its hub 25' loosely mounted on a stud 26 on a stand 14, see Fig. 5. A. helically coiled contraction spring 27 acts to yieldingly hold the lever 25 out of engagement with the ratchet gear 24, as shown in Fig. 3, or in engagement with the ratchet gear 24, as shown 1n Fig. 5.

The bobbins 5, which are forced toward the opening 18 ofthe magazine, drop with their butts 5' into a chute or guideway 14*, see Fig. 1, which in this instance is made integral with the stand 14,-,which chute is adapted to guide the bobbins 5 downwardly, and under the transferrer arm 11. A spring actuated latch 28 has its lip 28 extend under the lowest bobbin, and is adapted to hold the lowest'bobbin in place, and yieldingly move out of thepath of the but-t of the bobbin, when thelowest bobbin is to be transferred. The latch 28 has its hub-28" loosely mounted on a stud 29 on the stand 14, see Fig. 3, and a torsiorr spring, not shown, acts tov yieldingly move the latch 28. into position. Transyers'e rods 30, see Figs.

1, and 4, with tubes 30 thereon, are adapt/ed to connect the inner chute 14 with the outer chute 31, which outer chute is adapted to form a guideway "for the tips 5" of the bobbins, 5;.which drop toward the lower discharging end of the magazine. The lowest bobbin 5 rests with its'tip5" upon a latch 32, which is loosely mounted on a stud 33, and is yieldingly held in position by a'flat spring 34', see'Fig. 4. The outer end 19 of the magazine is provided with a spirally shapedopening or slot," through whichthe filling threads 5 extend. The filling threads 5 are guided over a guide frame. 35, and extend downwardly to a thread holder 36, so that theendsof the thread may be wound thereon, see Fig. 4. V

In Fig. 1 is shown. the spiral magazine in its.o crating position, after it has been supplie with bobbins or filling 'carriers'5d fwhich are to be successively transferre from the magazine to the. active shuttle upon the substantial exhaustion of filling in the active shuttle. The magazine is in this "instance held in its position by a.- spring actuated latch- 37, see Fig. 1, which has its hub loosely mounted on the transverse tube 30 on the rod 30, see Fig. 1'. The up er end 3'7 of the latch 37 ishook shape, an is adapted to engage with an extension 18 on after it has been emptied of the bobbins or filling carriers, the latch 37 is disengaged from tllQGXtEIlSiOIl 18",-to enable the magazine to be turned one-half of a revolution on the bolt 17, until the bar 38 on the magazine rests against a stop 14 on the chute exten sion 14* on the stand 14, as shown in Fig. 5.

Anew supply of bobbins or filling carriers is inserted at the open end of the magazine at 18, and 19*, and the pusher, slidingly held on the arms 21, is moved inwardly, and toward the center of the'magazine, while the ratchet gear 24 is retained and locked by the latch 25.

Itwill be understood that the details of construction of my improvements may be varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a, weft replenishing loom, a magazine for bobbins or filling carriers, having a spiral guide-way or groove for the bobbins, starting from the central part of the magazine, and a pusher to engage and move the bobbins toward the dischargingend of the magazine and under the transferr r.
